Celestial bodies are objects that exist in outer space, beyond the Earth's atmosphere. They can include stars, planets, moons, asteroids, comets, and galaxies. These bodies are governed by the laws of physics and interact with each other through gravitational forces. Celestial bodies play a significant role in the structure and dynamics of the universe, forming systems such as solar systems and galaxies. They can vary greatly in size, composition, and characteristics, and studying them provides valuable insights into the nature and evolution of the cosmos.
